To all whom it may concern:

Be it known that I, EDUARD.BACHMANN,'2\ citizen of the Republic ofSwitzerland, residing in Seebach, hem Zurich, in the Canton of Zurich,Republic of Switzerland, (whose post-office address is Seebach, nearZurich) have invented a new and useful Apparutus for the Production ofPictures, Patterns, and the Like by Photographical Method; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification.

1 have uppliedior patent in Switzerland on March 28th 1905, Patent No.31759; and in Germany on January 9th 1906, application No. 8199.

This invention relates to an apparatus for the production of pictures,patterns and the like by photographical method which pictures show asimilar reguable for preparing patterns forembroidery, for the engiavingof checks and the like.

One form of construction of the present invention is shown in theaccompanying drawings and two forms of a part of the some with patternsthat have been prepared thereby.

Figures 1 and 2 show a ground plan and a middle sectional elevationrespectively of one form of such part. Figs. 3, 4 and 5, plan,longitudinal section, and cross section respectively of the other form.Fig. 6 is :1 view of. the whole apparatus in partial section. Figs. 7 8,9 and 10 are patterns prepared by the apparatus.

The base plate 1 rests on a frame a, which carries a reflecting surfaceb sloped towards a source of light 0. The ground plate 1 has an openingand receives a frame 2 which carries the ground figure serving as basefor the production of various figures. A plate 4, is carried by fourcolumns, 3, fitted to the base plate 1. ..n objective 5, directeddownwards is arranged in the middle of the plate, 4, and can be coveredover by a flap, 6. A photographic camera, 7, is arranged above theobjective and has a back, 9, resting on a plate, 8.

The plates 4 and 8 may be moved relatively to each has a scale providedon a ring, 16, over which a pointer, l

17, fastened on the frame, 2, projects. The central.

l opening, 18, of the plate, 14, is for the most part covered over by adisk or mask, 19, firmly screwed to the plate, 14. The disk or mask, 19,has a recess or opening, 20, with a central angle of 45 while the scale,16, shows sixteen equal divisions. The opening, 20, is covered over by aphotographic negative, 21., which carries the ground figure and is heldto its support by clamps, 22. Four pins, 23, serve for fixing the frame,2, to the base plate, 1.

With the arrangement shown in Figs. 1 and 2, the photographic negative,21, on which a ground figure of any kind has beeh applied by hand, bymeans of a relief copying apparatus or a Rose-engine or the like, islaid on the mask, 19, so that that part of the ground figure which hasto be utilized for the production of the pattern is situated above theopening, 20, and is then fastened in the manner described. Then thewhole arrangement is placed on the base plate, 1, and is sealed fromabove against the light in the manner shown in Fig. 6, while the lightcoming from the source of light, 0, can enter through theabove-mentioned opening of said plate. The part of the ground figuresituated above the slot, 20, is then photographed and afterwards theobjective is covered over by the flap or cover, 6, and

present case this is taken corresponding to the'central angle of theslot, 20, viz., 45. The corresponding part of the ground figure is newagain photographed so that in addition to the picture already existingon the plate in the back, 9, the same pictureis directly photoformedconsecutively on this plate. As thus, how ever, taken together do not inthis special case form any figure complete in itself, theyare formed ona second plate in a similar manner. 'Both the plates are mirror pictureto those of the other plate and iso forth a photographed together. Thepattern shown in part in Fig. 7 is an example prepared in this manner.Instad of two ground figures of the same kind, two ground figures ofdifferent kinds preparedin this manner may be combined to form apicture.

flected. image) will be understood at once, if, for :instance, along thelower radius of slit 20 (Fig. 1) a fiat mirror is erected perpe'ndicularly to the picture surface. In the same manner as the pictureappearing in the mirror will join the bounded part of the ground figureof the. negative, the single pictures of the one photographic plate arejoined to those of the other photographic plate and then the plates arephotographed together as described. An endless number of variouspatterns may be formed from one and the same ground graphed beside it.In this manner eight pictures are then developed and so placed withtheir picture aids together, that the part pictures of the one plate fitas I rosette shaped figure and then both the plates are again the disk,14, turned through a certain angle. In the The meaning of the expressionmirror picture (refigure, according as one or other part of the same isplaced over the slot, 20, and according as this slot or its centralangle is larger or smaller. According to the displacement the partialfigures may be more or less interwoven or may be arranged at definitedistance from each other. For example, each second part of the scale maybe skipped over when exposing. From the first pattern produced from theground figure, according to the same process, the most numerousvariations can be obtained, as is shown by holding any desired part ofFig. 7 between two flat mirrors standing vertical to the plane of thepicture and arranged at an angle to each other, for

instance, if two flat mirrors are placed on the dotted lines on Fig. 7and held perpendicularly to the drawing,

a figure like that shown in Fig. 10 will appear in the murors, whichfigure is obtained on the photographic plate by photographing in themanner described the part of the ground figure which is-bounded by the,Either a separate'mask, 19, may be used for each slot,

20, or several slots may be arranged in the same mask. Further theconstruction may be such that for the purpose of producing a figure asshown in Figs. 7 and 8, after the firstround the mask, together withtheplate', can turn and then can be so adjusted by repeating the sameproeess that each new part figure is superimposed on the figure alreadyformed on the plate by the first exposure. This was done in the'firstprocess described by combining together the two part figures on the twoseparate plates. Furthermore, by dispensing with the mask, 19, the slot,20, can be arranged direct on the disk, 14, or the ground figure maybearranged in the mask, 19, itself without any special slot, 20. Thisground figure-can be transferred in the form of unconnected tracings orholes passing through the whole mask.

I Naturally the means for displacingthe mask as well as the form'of thelatter may vary from that described.

According to Figs., 3, -4 and 5 the frame, 2, has a carriage orJsIide,25, which can be moved forwards or backwards by means of crank, 26, andscrew spindles, 27', on which nuts, 28, work or turn. The slide, 25, hastwo flat rails, 29, situated across the frame, 2, said rails beingparallel to each other and are firmly clamped at both endsbetween thesmall plates, 30, carrying the nuts, 28, and can be moved asdesired'towards each other in the direction of movement of the slide,25. A scale, 31, is arranged on both sides of the frame, 2, in

order to be able to exactly measure the displacement of the slide, 25.On the rails is situated the photographic negative, 32, carrying theground figure, above which photographic negative two opaque strips, 33,are placed and like the negative, 32, are firmly held to the rails, .29,by the screws, 34. Under each of the rails, 29, is situated one end ofeach of two opaque covers, 36, the other ends of which are situated on aspindle, 35, arranged in the frame, 2. These covers can as desired bemoved with the slide, 25, or moved alone or wound up and down. A glassplate, 37, serves as support for them, which glass plate is held byangles, 38 on angle iron, 39, situated along the side walls of theframe, 2. Pins or studs, 23, serve for fixing the heme, 2, on the baseplate 1.

With the arrangement shown in Figs. 3, 4 and 5, the patterns may beproduced for example in the following manner, the principle of whichwill be understood by observing a fgure between two mirrors parallel toeach other. The ground figure is successively drawn along under theobjective and photographed. When one has thus prepared a strip ofdesired length on the photographic plate, the plate is developed andthen tightened up in place of the plate, 32', so that this negativeserves as ground figure. This strip is then photographed in a similarmanner, so that finally a complete rectangle results (see Fig. 9). Ifthe ground figure itself is of oblong shape, then the desired patterncan in certain cases be prepared in one course of the slide, 25. Withthis arrangement also the most varied figures or patterns may beproduced, when for example, only a fractional part of the ground figureis photographed; or when moving along the same, even when the wholeground figure is exposed by an amount which is smaller than theextension of the same in the direction of the motion, as was done inproducing the pattern shown in Fig 9. It also serves for arrangingvarious pictures or drawings on each other on the same plate, such forexample as may be desired for producing a number of smaller negatives onone large plate for the purpose of reproduction in photolithography,

autotypy and the like. There is also the great advantage of being ableto expose pictures, which finally have to be arranged on the one and thesame plate, for various periods corresponding to their variouscharacters. In this method a fresh picture is inserted as ground figureeach time the arrangement is moved.

The patterns produced with the device according to Figs. .1 and 2 may befurther extended or vice-versa with the arrangement above described.Here also the individual parts may be modified in their arrangement andconstruction as desired.

The whole apparatus may be so constructed that it can be usedhorizontally and in certain cases, as for example when using a constantsource of light, the exposure may be effected directly.

Quite irregular figures may be used as ground figures, as also variousformations, suchas flowers and parts of plants, according to the objectone has in view. The transfer of the ground figure on the sensitiveplate can also be made by contact, in which case the objective is notemployed.

The pictures produced by this apparatus may be of What I claim is:

1. In an apparatus of the class described, the combinatlon with acamera, of a movable support tor a ground figure to be photographed, andmeans for moving such support determined successive distances withrelation to the camera to permit repeated sharply adjoining, more orless interwoven'or' disconnected photographic impressions to be takenthereof upon a single sensitive surface.
